The flanges 20 which will be indicated in the following claims. 9 areprovided with gear teeth II which mesh 20 In the accompanying drawingsin which are with teeth on a common pinion l3 which is atillustratedseveral of various possible emboditached to andunder control of acontrol knob Heretofore, many automotive heaters have been frictionalclamp members 23, detailed in Fig. 6. made of a shape wherein, the corehas had a Each clamp member 23 comprises a slot 25 which verticaldimension not less than the horizontal springingly engages innergudgeons 21 of parallel dimension thereof, and usually, this verticaldireaches of relatively rigid rods 29.

' their respective clamps 23 and 26 maintain a given adjustment. Thisadjustment is independent of the adjustment at knob l5.

In Fig. 8 isshown an alternative drive for the rings 1 consisting of apinion 31 driven from said knob l5, which, while it is' meshed with oneof the gears of one of the rings 1, has clearance at' its addendum withthe addendum of the teeth of the other ring I. However, the pinion 31is" meshed with an idler 39 which in turn meshes with the ring I notmeshed with by the pinion 31. By this alternative construction, it ispossible with a single rotation of the knob [5 to cause the rings 1 torotate in opposite directions. From" the above, it will be seen thatwitha single turn of the knob I5, the rings may be simultaneously rotatedeither with the deflectors 35 outwardly adjustedor closed. l

The radiator core per se is shown atnumeral' 4!. ,From Fig. 4 it will beseen that the shield l hasagenerally rectangular shape, with thecylinders 3 bulging therefrom. The rectangular shape accommodates thegenerally rectangular shape ofthe core but this leaves arcuate portionswithin the cylinders 3 which are difiicult to fill in with core materialand which if not filled, permit passage. of cold air. Therefore, thecore is provided with arcuate, air-blocking fillers 443, as shownin Fig.9 which fit into the arcuate portions of the cylinders.

' Behind the enclosure shield l is an enclosin "*member45 which isfastened tothe shield by screws 4'! (see Figs. 1 and 2). The enclosingmember has bolted thereto a supporting bracket 48. This bracket hasrigidly fastened thereto threaded bushings 49 for loosely accommodatingrespectively an inlet pipe 5| and an outlet pipe 53, the pipes 5| and 53passing to the usual upper and lower tanks 52 and 54 respectively of thecore 4!, The pipe '5i attaches to the upper tank at the upper left-handregion of the heater (viewed from the rear), and the pipe 53 attachesenclosing member 45 and projects the airthrough the core 4| and outthrough the two openings 5 2,096,20 V I V in the rings I provided thewings 35 are adjusted to open position. From the above-it will be seenthat the fan. draws a'single stream of air into the opening in theenclosure, 45 which branches out into two streams emanating from therings 1,

each stream being individuallycontrollable as to lateral and verticaldistribution. If desired, one stream may be cut off entirely, or both..i.

It will be seen from Fig, Qthat not only do the inletand outlet pipes 5|and "5 3"have arelative' diagonal relationship with respect to theheater,

movementsof the heater under jarring action mm the automobile? It willbe seen that the shield l and the member [4'5 formanen'casementenclosure for the core 4! which also functions as a support. The forwardiace'bf'th'e core is aligned by suitable stops E9 (Fig; 4); Thisenclosure has a single-opening in-Q let and a plurality ofoutlet-openings constituted by the rings 1.

In View of the abovefitwill he as that the several objects of theinvention are achieved and otheradvantageous results attained. As manychanges could be made in; carrying outthe' above constructions withoutdeparting from the scope of the invention, it is intended that allmatter contained in the above description or shown in the accompanyingdrawings shall beinterpreted as illustrative and not in a limitingsense. 7
